GARDZ Problem Surface Sealer

I used Zinsser Gardz on a wall that had been damaged by wallpaper removal, and I was blown away by the results. This stuff penetrates and seals porous, chalky, or damaged drywall like a dream. It dries clear and hard, creating a solid base for paint or wallpaper adhesive. The application was easy—just brush or roll it on. It’s low odor, water-based, and dries quickly. I noticed it locked down residual adhesive and prevented bubbling when I painted over it. It also helped even out the surface texture, which saved me from having to skim coat the whole wall. If you’re dealing with peeling paint, torn drywall, or old wallpaper glue, Gardz is a must-have. It’s not flashy, but it’s incredibly effective. I’ll definitely keep a quart on hand for future projects.

I was not able to find this at the local Lowes or Home Depot, which really surprised me. Had to get it here. After viewing several YouTube videos this sealer was suggested by the majority of the painters. I removed a chair rail and when I was removing it from the wall, the paint came with it and tore the sheetrock paper in several areas. Sheetrock is covered by about 6 or 8 layers of brown paper before you get to the actual "chalk" like gypsum core. and you have to seal it to keep it from blistering. Moisture from joint compound (Mud) gets trapped behind the tape or paper surface, causing it to separate from the gypsum. It is easy to apply, I used a small paint brush. It has the consistentcy of watery glue so be careful when applying it or you will have it all over. It covered the areas easy. If you can buy the quart size I recommend it, a little goes a long way. I let it dry over night and came back the next day with the "mud" to cover the torn paper areas. It worked great, I had no "blisters" come up on any of the paper at all. And I had never "mudded" before , ( I was scared to death to try) but found out it is easier that it looks(always use a metal drywall knife or trowel that is at least 4 to 6 inches wide. Plastic trowels don't work as well. I got a quart of the ready made mud and it turned out great. Walls are smooth and paint went on super easy. (24 hours for the joint compound to dry)

I had 20 year old wallpaper, lining paper and paste to remove and then paint the walls - easy, right?!? I removed it with a steamer, paste remover, hot water and softener...you name it. It was the worst wallpaper removal of my life and left me with a wall that was pitted, torn, and riddled with solid paste I couldn't remove even with thorough sanding. I couldn't sand any more because it was tearing the drywall paper too deep and couldn't wet anymore because it was ruining the drywall... Catch 22! I read about this product and had nothing to lose by trying. I patched the large tears then sanded the wall one last time, cut away any peeling or curling drywall paper, wiped with a lightly damp rag and clean water to remove dust - then i let it dry completely. I then said a quick prayer and got to work. It is a cloudy white/blue, very liquid product. I used a medium nap roller that I was happy to toss after using it (incase cleaning didn't work!). At first I made a drippy, sloppy mess which was easily wiped up. The consistency is very different to paint. I quickly caught on that if the roller is full, light pressure is all I needed combined with slow rolling motion to avoid a ridiculous amount of splatter. After I "got" it, the job went very quickly! I waited for it to dry and touched up any areas that didn't match the shiny-ish finish it has when dry. I didn't have much to touch up because it as pretty easy to see missed spots when I was applying. I chose not to do a second coat as the wall was now solid. I then applied a texture onto the wall (thinned mud applied with a roller). It adhered very well to the gardz. Once dry, I applied a second coat of gardz to the texture. My wall was off white /yellow, with some patches, but I knew the paint would apply evenly because the surface was sealed, so I chose to apply a paint/primer in one from sherwin Williams. I needed only one coat and the finish was completely even and perfect! This is a wonderful product. I did have paste left on the wall (not a ton) - it sealed it. I had a mud texture (dried) -it sealed it. I had damaged drywall that would have been a huge undertaking to patch and flatten -the gardz helped me do that and avoid drywall patches. Other major bonus - this is not oil based!!!!!!!! It also cleans up easy if done immediately after spill or use. After that - never going to happen.

Excelente sellador de humedad. Me ayudo mucho con humedad que tenía en el baño. Lo súper recomiendo.

Excellent product for sealing up damaged drywall. I used it to help repair the wall after removing the tile backsplash in the kitchen. It sealed up the exposed paper and gypsum without causing it to soak in and lift away. Highly recommend for this type of repair.

This is truly a miracle surface sealer. I had badly crumbled drywall, with the paper gone in patches. Was unwilling to re-drywall so I followed instructions, sanded it down and painted it. You'd never know the problem area was there.

My drywall paper peeled when prepping a room for painting. This sealer worked for coating the area prior to priming. I would recommend it. Seller was fast at sending the item!

Helps glue all the drywall in place so fixes hold better. Water based so don't leave outside in shed during winter.
